Title: Ribbon-controlling method for serial printer
Inventor: TAKEBU SHIGERU
IPC: B41J35/10
Filed: 1986-10-31
Abstract: PURPOSE:To prevent color misregistering from occurring due to external forces, by moving a ribbon position in a direction perpendicular to a feeding direction to a most stable position when all data in a reception buffer is printed and the lapse of time reaches or exceeds a predetermined period of time. CONSTITUTION:A master CPU 1 drives an I/O driver 4 through a bus line 5, thereby controlling an interface circuit for external devices and a line-feeding motor which are connected to the I/O driver 4. It is monitored whether printing of all received data in a RAM 3, which tentatively stores data received from the host side, is completed, and the lapse of time from the reception of the last data from the host by the RAM 3 is monitored. When it is found by monitoring that all received data in the RAM 3 is printed and a predetermined period of time has elapsed from the reception of the last data, the master CPU 1 performs such control as to move a wide ribbon to a most stable position. With the ribbon moved to the most stable position, it is possible to effectively prevent color misregistering due to external forces from occurring at the time of color printing.

Abstract: PROBLEM TO BE SOLVED: To record with sufficient intensity and to reproduce at a high S/N ratio by using a solid immersion lens. SOLUTION: At recording, a voltage is not applied to a liquid crystal plate 631. Then, all laser beams LB are converged on the bottom surface 634a of a solid immersion lens 634, and by bringing a recording medium RM close to the bottom surface 634a, a near field beam is generated, and such a laser beam LB is controlled, and the information is recorded with sufficient light intensity. At a reproducing time, a prescribed DC voltage is applied to the liquid crystal plate 631. Then, the central part of the laser beam LB is shielded by a polarizing plate 632, and only the beam of the outer peripheral part of the laser beam LB made incident on the bottom surface 634a of the solid immersion lens 634 at an angle larger than a critical angle arrives at the solid immersion lens 634 to generate the near field beam downward it.

Filed: 1992-09-28
Abstract: PURPOSE:To enhance output by specifying the relationship between the wavelength at the frequency of transfer rate and the distance from the center of magnetic gap to the edge in the direction of thickness of a magnetic layer. CONSTITUTION:A magnetic layer 5 for forming a magnetic gap (g) is applied through a nonmagnetic gap spacer 7 onto a magnetic substrate 1 while opposing to a surface 6 which opposes to a magnetic recording medium, thus constituting a thin film magnetic head in which a magnetic circuit is established passing through the magnetic layer 5 and the magnetic substrate 1. Assuming the relative speed between the magnetic head and the magnetic recording medium is V and the highest repeating frequency in digital magnetic recording or the half of transfer rate frequency is fs, a relationship of 0.83lambdas<b<1.33lambdas is set between the wavelength lambdas and the distance (b) from the center of the magnetic gap (g) and the edge in the direction of the thickness of the magnetic layer 5. According to the constitution, output from a reproducing head can be enhanced in digital magnetic recording by taking advantage of the beating effect in the frequency characteristics of the thin film magnetic head.
